Kylie to appear on 'X Factor' final

Kylie Minogue is to appear on the final of The X Factor, the show's producers have confirmed.

The resurgent pop princess will perform a duet with Leon Jackson, one of two finalists to be mentored by her sister Dannii.

Kylie will also perform 'Wow', the second single from her X album, which is to be released in February.

Jackson won't be the only finalist to duet with a celebrity partner. Welsh opera diva Katherine Jenkins will sing alongside Rhydian Roberts, while Same Difference will be joined onstage by Minogue's former Neighbours colleague Jason Donovan.

The final of The X Factor airs Saturday at 7.15pm on ITV1.
